Remember the gorgeous Luminous Engine tech demo Square Enix showed off three years ago? The firm showed it again at Microsoft’s Build Conference, this time utilizing DirectX 12.

The Witch Chapter 0 [cry] real-time tech demo was created from research Square conducted using real-time CG technology and DX12 in collaboration with Microsoft and Nvidia. The results of this research “will be incorporated into” the Luminous Studio engine for use in future game development.

Witch Chapter 0 was created mainly by the developers of Agni’s Philosophy – Final Fantasy Realtime Tech Demo with more refined graphics and improved processing capabilities.

“Our team has always pursued cutting-edge pre-rendered and real-time CG,” commented Hajime Tabata, head of the next-generation technology research project at Square Enix.

“As a part of the technical development, we created this demo using world-class, real-time CG technology with generous support from leading-edge software and hardware providers – Microsoft’s Windows10/DirectX 12 and NVIDIA’s GeForce GTX. The efforts from this project will power future game development as well as FINAL FANTASY XV, currently a work in progress.”

The card used, according to Square, was Nvidia’s GeForce GTX TITAN X-4-way SLI on PC.
